ok My mom got my grandma an adult cake for her 50th well my mom's 50th is in a few months and my grandma wants paybacks... I plan on having the guy between the boobs... but i want the guy to have a hiden special effect... I am kinda at a loss with how to achive this.. here is my idea ... taking a plastic tube filling with white frosting and inserting it through then under the cake.. and then using a can of air to make the frosting shoot out of it.. kinda like a can of silly string... but not sure if the can of air would be strong enough to achive it... i dont want to draw attion to it, i thought about using an air compressor but they are loud... Any ideas??
